In this example, the new value is 20 percent. The number must be integer.
5. Save the file. The new setting will take effect at the next backup. No service restart is needed.
4.7.15 Media components
This option is effective for both Windows and Linux operating systems, when the backup destination
is CD, DVD, or Blue-ray Disc (BD).
When backing up to this media, you can make this media work as regular Linux-based bootable
media (p. 432) by writing additional components to it. As a result, you will not need a separate
rescue disc.
The preset is: No bootable components.
Choose one of the following components you want to put on the bootable media:

Acronis Bootable Agent is a bootable rescue utility (based on Linux kernel) that includes most of
the functionality of the Acronis Backup agent. Put this component on the media if you want more
functionality during recovery. You will be able to configure the recovery operation in the same
way as under regular bootable media; use Active Restore. If the media is being created in
Windows, the disk management functionality will also be available.

Acronis Bootable Agent and One-Click Restore. The One-Click Restore is the minimal addition to
a disk backup stored on removable media, allowing for easy recovery from this backup. If you
boot a machine from the media and click Run Acronis One-click Restore, the disk will be
immediately recovered from the backup contained on the same media.
Caution: Because the one-click approach does not presume user selections, such as selecting volumes to
recover, Acronis One-Click Restore always recovers the entire disk. If your disk contains several volumes and
you are planning to use Acronis One-Click Restore, include all the volumes in the backup. Any volumes
missing from the backup will be lost.
4.7.16 Mount points
This option is effective only in Windows for a file-level backup of a data source that includes
mounted volumes or cluster shared volumes.
This option is effective only when you select for backup a folder that is higher in the folder hierarchy
than the mount point. (A mount point is a folder on which an additional volume is logically attached.)

If such folder (a parent folder) is selected for backup, and the Mount points option is enabled, all
files located on the mounted volume will be included in the backup. If the Mount points option is
disabled, the mount point in the backup will be empty.
During recovery of a parent folder, the mount point content will or will not be recovered,
depending on whether the Mount points option for recovery (p. 162) is enabled or disabled.

If you select the mount point directly, or select any folder within the mounted volume, the
selected folders will be considered as ordinary folders. They will be backed up regardless of the
state of the Mount points option and recovered regardless of the state of the Mount points
option for recovery (p. 162).
